Smaller, high efficiency controllers. Our portfolio of high-performance synchronous rectifier controllers enables higher efficiency for power supplies by replacing the output rectifier diode with a more efficient synchronous rectifier field-effect transistor. This topology helps you create solutions that are smaller, cooler and compliant with stringent efficiency requirements.
